The Jade templating code in `views/quotes.jade` will now check against the Regular Expression which has been added to `snippets.js` and is delivered to the template by `modules/web.js`. The reguar expression used should be able to handle any URL and ensure no non-URL elements are made into URLs. It may be worth adding checking for 4XX error codes at a later date. This shouldn't affect any of the other modules; features have only been added, not modified.
